pose intended; inqother words, if such parts could be so supported thatthe wear due to vibration could be avoided, the period of their "usefullife could be greatly extended. One such part is the common loop-typebrake hanger which has long been supported from a well known type ofbracket having a jaw at the end thereof within which the top member ofsaid hanger is supported. Numerous types of wear plates for such jawshave been devised and various means of resiliently supporting the hangertherein have been tried. e

An object of vmy invention is to devise an 25 arrangement of a loop-typebrake hanger supported from a jaw-type bracket which will dispense withall wear on the hanger at the point of support.

My invention comprehends furthermore an 30 arrangement which will permitthe ready replacement of the resilient means in which the hanger issupported whenever the resilient quality of such means shall havedeteriorated to the, point where it is no longer useful.

' y invention further contemplates a resilient means of supporting suchabrake hanger so that at the point of support said hanger will be freeof engagement with any other metal part, thus Ipreventing frictionalwear thereof.

In my novel arrangement the hanger is supported from resilient materialand said resilient material is placed under sufiicient compression sothat all the parts are tightly fitted against each other, thus reducingto a minimum destructive vibration and preventing altogether the noiseand chatter which commonly results as playdevelops between engagingmetal parts.

These and various other objects will be more apparent from the followingdescription of sev- 'eral modifications of my invention and from theappended claims.

Describing my invention in greater detail and referring moreparticularly to the modification shown in Figures 1 to 8, the truckframe member 2 has the integrally formed brake hanger bracket 4reinforced .by the vertically arranged central rib 5 and terminating ina jaw-like structure having the top and bottom flaring walls 6 and 8forming therebetween the opening 9 recessed at the rear as indicated atIll, said recess being defined further by the lateral walls H and I3.Received within the jaw opening 9 is the horizontal top member l2 of mynovel .brake hanger 14, said brake hanger being of the loop- Figures '7and 8, said retaining plate having the 5 central cylindrical portion 24with the generally vertically arranged opening 26 receiving theretaining key or cotter 28, said cotter also extending through thealigned openings 38 and 32 (Figure 4) formed in the before mentioned topand bottom walls 6 and 8. The cotter 28 has a tapering end of usual formas best seen at 29 (Figure 2) so arranged to accommodate its forcibleinsertion into position'against the retaining plate 22, thus compressingsomewhat the bushing I 8.' The bushing I8 is positioned at itsextremities against the complementary curved forward edges of thelateral walls I! and I3 as best seen at 34 (Figures 2 and 4), said wallsthus providing means against which the bushing may seat.

The bushing I8 is shown in detail in Figures 5 and 6 wherein it may beobserved that it is of generally cylindrical form having the centralopening 36 and the slot 38 at one side thereof, said slot being formedto permit the insertion of the top member I2 of the brake hanger, saidmember being inserted by distorting the rubber bushing suiflciently toforce said member therein. Centrally formed at the slotted side of saidbushing is the arcuate channel 40 against which may be seated as at 20the inner face of the cylindrical 5 portion 24 on the retaining plate22.

The form in detail of the retaining plate 22 is shown in Figures '7 and8. It will be noted that the plate is of somewhat arcuate form as bestseen in the end view of Figure 7 having the central channel indicated at42 forming seating means for the full length of the bushing I8 at theslotted side thereof. The said channel 42 is broken centrally thereof bythe before mentioned cylindrical portion 24 which forms a key way for:the cotter 28 and the inner wall of the cylindrical portion 24 isreceived within the channel 40 on the bushing I8 as already described.

In this embodiment of my invention it will be observed that I haveprovided a novel form of securing means for a loop-type brake hangerwherein all the parts are tightly fitted and no free play is permittedtherebetween.

In the embodiment of my invention shown in Figures 9 to 16, inclusive,the truck member 44 ,has the integrally formed brake hanger bracket 46reinforced by the centrally formed top rib 48, said bracket terminatingin the jaw-like structure substantially identical to the embodimentpreviously described and having the flaring top wall 50 and the flaringbottom wall 52 forming therebetween the jaw opening 54 (Figure 4) havingat its rear the cavity 56 further defined by the lateral walls 58 and58, the forward edges of said lateral walls 58 and 60 (Figure 9) havingan I arcuate configuration (Figures 10 and12).

ceived in said jaw opening 54 is the loop-type brake hanger 62,'the topmember 64 thereof being encased in the rubber bushing 66 of novel formmore particularly described hereafter. The back or rear wall of saidbushing isof generally cylindrical form and at its extremities seats asat 68, 68 against the arcuate forward edges of the lateral walls 58 and80. The outwardly directed face of the bushing is of the configurationbest seen ln'Figure 13, and of com- I plementary form with the retainingplate III which is seated there-against, said retaining plate forming ameans of abutment for the cotter pin I2, said cotter pin; being receivedin the aligned openings I4 and I6 formed respectively in the top andbottom walls 58 and 52.

7 The form and detail of the bushing 66 is shown in Figures 13 and 14.It will be noted that the bushing is of generally cylindrical form withthe central opening I8 within which the top member of the brake hangermay be seated by distorting the bushing, said distortion being permittedby the slot 88 centrally formed in the outwardly directed wall of saidbushing. The configuration of said outwardly directed wall is ofirregular form as seen in Figure 13 and complementary to the form of theretaining plate I8 against which it is seated. Said bushing has thecentrally formed vertical channel 82 receiving the channel portion 84 ofthe retaining plate 10, said channel iortion beingv formed toaccommodate the cotter The detail of the retaining plate 10 is shown inFigures 15 and 16. It will be noted that the configuration iscomplementary in form to that of the outer face of the bushing 66. Thecentral chan-- nel portion 84 is flared as indicated at 86, 86 (Figure15) to accommodate insertion of the cotter lit; the said flaringstructure permitting the tapering ,end of the cotter I2 to be insertedthrough the opening in the top wall of the jaw and tobe forced into thecentral channel 84 of the retaining plate thereby compressing somewhat,by this,v

operation, the rubber bushing 66 so that all of. the parts will be intight engagement with each other.

In this second embodiment of my invention it will be noted likewise thatall the parts are firmly seated against each other so as to eliminateall free play therebetween.

In the embodiment shown in Figures l'l to 20,

bracket terminating in a novel form of jaw 94 designed particularly forreception of my novel i form of brake hanger 96.

The said jaw 94 is of hook-like form as viewed in the side elevation,

the rear wall thereof being of generally cylindri-' cal formation andthe top wall thereof terminating at 98 where the juncture is formed withthe before mentioned reinforcing top rib 92. The said cylindrical rearwall presents an inner face complementary in form'to the side wall ofthe bushing I90, said bushing encasing the top member I82 of the brakehanger 96. Inwardly of the jaw 94 the flange 92 has an opening thesecuring bolt I08, theopposite end of said securing bolt being receivedin the aligned opening I 98 formed in the retaining plate II 0, securingmeans for said bolt being in the form of the threaded nut 2- which maybe drawn up tight against the nut locking angle plate II4 which isflanged over as at I IE to abut the end of the re-f taining plate H0 andmay be flanged over at the. opposite end as at I I8 to lock said nut inplace.

The bottom wall of the jaw 94 is horizontally extended as at IZIJ'andprovided with gular slot I22 for reception of the tongue I24, saidtongue I24 being inserted in the slot after the bushed brake hanger hasbeen applied in the IU4 receiving the rectan;

brake hanger 98 and thereafter the securing boltv 1.

tight to retain the parts'in place. I

. 2,232,468 Inthis modification the bushing mu is sleeved upon the topmember'of the'hangr although, if

desired, it may beformed with'a slot as in previous modifications.' Inthis modification, as

I shown, theb'ushing M10 is unslott ed and is a solid cylinder of rubbercomposition material, the inner wall of which may be seated as at I26(Figure 20) against the inner wall of the jaw 94 being complementarytherewith and the front wall thereof may be seated as at I28 against thecentral portion of theretaining plate lIiLsaid cen-- tral'portion beingof arcuate form as at I30'with an inner face complementary tosaidbushing.

To those skilled in the art it will be readily apparent that in thefirst two modifications described I have adapted my novel brake hangerand retaining plate to a well known type of AJA. R; standard brakehanger jaw. In'the" last modification described, however, I havedesigned a form of jaw and retaining'plate therefor most eflicient formy novel form of brake hanger.

It is to be understood that I do not wish to be limited by theexactembodiments of the'device shown-which are merely by way ofillustration and not limitation as various andother forms of the devicewill, of course, be apparentto those skilled in the art withoutdeparting from the or the scope of the claims.
